You can choose between two sorting modes in Lambus:
1. Automatic Sorting
In the automatic sorting mode, your waypoints will rearrange automatically when you add, change or delete a waypoint. The itinerary and your map changes as well. This is useful if you already know where you will be.
2. Manual Sorting
In the manual sorting, waypoints remain in the order in which you added them. This is useful for sketching your trip together in the beginning. You can rearrange them by tapping "Edit" in your itinerary and then drag and drop the waypoints via the "☰" icon on the right.
Alternatively, you can tap on the waypoint number and enter the new number in the text field that pops up :).
Switching between Automatic and Manual Sorting
You can easily switch between the sorting modes by going to your trip settings (the gear icon at the top right) and tapping on "Waypoint sorting" to select between "By Date and "Manual"
To rearrange waypoints manually, see the following video for details:
